Connection structure for a gardening implement

ABSTRACT

A connection structure is designed to connect the blade and the handle of a gardening implement and is formed of a connection rod, a control member, a locating head, and two steel balls movably contained in the recess of the control member and the locating holes of the locating head. As the control member is rotated to locate the connection rod which is fastened with the blade, the steel balls are forced by the control member in motion into the locating holes of the locating head. The blade and the handle are separated by rotating the control member in such a manner that the steel balls are forced back into the recess of the control member.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates generally to a gardening implement, and more particularly to a connection structure of the gardening implement.

[0003] 2. Description of Related Art

[0004] The gardening implements, such us shears, spade, rake, etc., are generally formed of a blade and a handle which is fastened at one end with the blade such that the handle is an integral part of the blade. In light of the nature of the connection structure connecting the blade and the handle, the handle is compatible with a specific blade. In other words, the handle can not be reused along with other types of the blades.

BRIEF SUMMARY OF THE INVENTION

[0005] The primary objective of the present invention is to provide a connection structure for connecting a blade and a handle of a gardening implement. The connection structure comprises a connection rod, a control member, a locating head, and two steel balls. The steel balls are contained in the control member and the locating head before the connection structure is joined with the handle of a gardening implement.

DETAILED DESCRIPTION OF THE INVENTION

[0014] As shown in all drawings provided herewith, a connection structure 10 embodied in the present invention is designed to connect a blade 20 and a handle 30 of a gardening implement. The connection structure 10 of the present invention comprises a connection rod 11, a control member 12, a locating head 13, and two steel balls 14.

[0015] The connection rod 11 has a connector end 112 which is provided with an annular tangent slot 111 and two retaining blocks 14. The connection rod 11 is further provided in an appropriate position with a fastening hole 115.

[0016] The control member 12 is of a tubular construction and is provided in the inner wall with a recess 121 and a position confining slot 122.

[0017] The locating head 13 is provided at one end with two locating holes 13 1, two cuts 132, and a position confining block 133.

[0018] The two steel balls 14 are disposed in the two locating holes 131 of the locating head 13. The locating holes 131 are preferably conical in construction.

[0019] The blade 20 of the gardening implement is fastened with the connection rod 11 of the connection structure 10 by a fastening screw which is engaged with the fastening hole 115 of the connection rod 11. The handle 30 of the gardening implement is fastened with the locating head 13 in conjunction with the steel balls 14 and the control member 12. The retaining blocks 114 of the connection rod 11 are retained in the cuts 132 of the locating head 13. As the control member 12 is retained, the control member 12 and the locating head 13 are confined in the spaces of the position confming block 133 and the position confming slot 122, as shown in FIG. 8. The steel balls 14 are thus forced by the control member 12 into the location holes 131 of the locating head 13, thereby locating the annular tangent slot 111 of the connection rod 11, as shown in FIG. 4. The blade 20 can be separated from the connection structure 10 of the present invention by rotating the control member 12 in such a manner that the steel balls 14 are forced back into the recess 121 of the control member 12, as shown in FIG. 5. As a result, the blade 20 and the handle 30 of the gardening implement are separated.

[0020] The connection rod 11 is provided at one end with a hanger 113 opposite in location to the connector end 112 of the connection rod 11. The hanger 113 is intended to facilitate the hanging of the blade 20 for easy storage, as illustrated in FIG. 6.

[0021] The embodiment of the present invention described above is to be regarded in all respects as being merely illustrative and not restrictive. Accordingly, the present invention may be embodied in other specific forms without deviating from the spirit thereof. The present invention is therefore to be limited only by the scopes of the following claims. 

I claim:
 1. A connection structure for connecting detachably a blade to a handle of a gardening implement, said connection structure comprising: a connection rod having a connector end, said connector end being provided with an annular tangent slot and two retaining blocks, said connection rod further having a fastening hole engageable with a fastening screw; a control member of a tubular construction and provided in an inner wall with a recess and a position confining slot; a locating head provided at one end with two locating holes, two cuts, and a position confining block; and two steel balls movably contained in said control member and said locating head; said connection rod being fastened with the blade of the gardening implement by the fastening screw which is engaged with said fastening hole of said connection rod, with the handle of the gardening implement being fastened with said locating head in conjunction with said steel balls and said control member, said retaining blocks of said connection rod being retained in said cuts of said locating head whereby said control member is rotated such that said control member and said locating head are confined by said position confining block of said locating head and said position confining slot of said control member, and that said steel balls are forced by said control member in motion into said locating holes of said locating head, so as to locate said connection rod, the handle of the gardening implement being unfastened with the blade of the gardening implement by rotating said control member in such a manner that said steel balls are forced back into said recess of said control member.
 2. The connection structure as defined in claim 1, wherein said locating holes of said locating head are of a conical construction.
 3. The connection structure as defined in claim 1, wherein said connection rod is provided at one end with a hanger fastened therewith such that said hanger is opposite in location to said connector end of said connection rod whereby said hanger is used to facilitate the hanging of the blade of the gardening implement.
